Title: Encapsulation device for speed limiting device for engine
Inventor: FUJII SATOSHI
IPC: F02D31/00
Filed: 1994-06-17
Abstract: PURPOSE:To ensure encapsulation of a speed limiting device and to block alteration operation by a method wherein the sped limiting device rushes an inner chamber from a moving-aside chamber recessed in a support wall fronting on the inner chamber, the limit operation part of the speed limiting device is contained in the moving-aside chamber, a closing plug device is engaged with the moving-aside chamber, and a governing lever is brought into the press part of the speed limiting device. CONSTITUTION:An inner lever 21 contained in the gear chamber 20a of an engine body is formed in such a manner that a speed is limitable by a speed limiting bolt 10. The limit operation part 11 of the speed limiting bolt 10 is moved aside to a moving-aside chamber 22 recessed in the front wall of a gear case and thereafter, the moving-aside chamber 22 is sealed with a bowl-form plug 23. Thereby, after an engine is delivered, the presence itself of the speed limiting bolt 10 can not be recognized, contact with the limit operation part 11 is impracticable to make, and alteration operation of the speed limiting bolt 10 is blocked. Thus, since the speed limiting device is shielded with combination of the moving-aside chamber and the closing plug device, it is impossible for a worker to make contact with the speed limiting device, resulting in holding a sealing state on the low speed and the high speed side during delivery.

IPC: G05F1/56
Filed: 1985-06-19
Abstract: PURPOSE:To control very exactly a reception level, based on a digital value which has been set multi-stepwise, by controlling the reception level by controlling a current control type attenuator by a current controlling circuit. CONSTITUTION:A CPU 1 compares a digital value D1 of a DC voltage which has beem made to pass through an A/D converter 5 and a digital value D2 which has been set in advance, and generates a pulse signal e1 in case of D1<D2, and sends it out to an integration circuit 2. The circuit 2 sends a DC voltage E2 which has integrated the signal e1, to an operational amplifier Q1 in a current controlling circuit 3. In this case, a control current i1 flowing to an FET Q2 becomes i1=(V-E3)/R2, therefore, it is controlled exactly by the voltage E2. A current control type attenuator 4 has a variable impedance circuit in which the impedance of a point P is varied by the current i1 flowing to diodes d1, d2, therefore, the input signal-to-output signal is controlled by a value of an impedance value (namely, the current i1) of the point P. Said consecutive operations are executed continuously.
